Popular psychology is full of myths and misperceptions. Money does buy happiness (if you know how to spend it). We like people who are like us (though, often, people who are complementary attract.) And saying, "Before others can love you, you have to love yourself," is ridiculous, and makes zero sense.

When I did my master's research on adult playfulness and leisure skill development, I spent, like, forever trying to recruit 60 people to participate in a study. Then I entered the startup world and learned about CRM (customer relationship management) software, marketing automation -- and even just A/B testing (sometimes called split testing), which is when you compare two versions of a web page (or marketing email, or whatever) to see which one performs better. This allows you to maximize your reach and chances of success by making data-driven decisions.

Love is pretty much the greatest thing ever. People who don't understand evolution think sex is the most important thing ever -- but without love, our species wouldn't exist. It doesn't matter how many women you can knock up if no one loves or cares for anyone and all the babies die.

As such, we evolved to be acutely sensitive to loneliness (and other negative emotions, like jealousy). And we evolved to love love.

Sometimes, spaces look playful... but you can't actually play in them.image: reddit​

Don't get me wrong. I love ball pits as much as the next guy. I spent pretty much every afternoon of my childhood at Chuck E. Cheese (and, unlike kids today, I actually got to run around and play by myself while the parents drank pitchers of beer). I'm all about play, and I'm stoked that so many Silicon Valley startups want ball pits.

But here's the thing: many designers and office managers think their job is complete once they've got that ball pit installed.

You're entitled to your own opinion. But you are not entitled to your own facts. Which is why I'm taking the time to point out some of the reasons that words are not violence -- and that there is truth to the old rhyme, "Sticks and stones can break my bones, but names will never hurt me."

​No, but actually. For real. Kids these days are more sensitive and fragile than kids of the past. Even according to the president of an elite university that I spoke with recently, “Today’s college students are not like you.”

So you've been asked to give a speech, talk, or assembly. And you want it to be memorable. You want your audience to think -- to feel something. To question their entire worldview, perhaps.

Now you just need a topic.

Skip the boring cliches. No one wants to hear you talk about abortion, the death penalty, gun rights, or minimum wage. These are huge and broad topics, and you're not an expert. You'll put your audience straight to sleep.
